介绍了国家博物馆兼顾文物保护、参观者舒适感和运行调节手段确定室内环境参数的原则。分析了采用部分负荷冰蓄冷、大温差低温冷水系统在负荷保证、提高除湿能力和节能方面的优势。结合CFD模拟,采用了分层空调加地板辐射供冷的空调系统以改善高大空间的室内环境。探讨了博物馆中文物库房和展厅恒温恒湿空调系统的设计方法。
This article introduces the principle that the National Museum should take into account the protection of cultural relics, the comfort of visitors and the means of adjustment for operation to determine the indoor environmental parameters. The advantages of partial load ice storage and large temperature difference low temperature cold water system in terms of load guarantee, dehumidification capacity improvement and energy saving are analyzed. Combined with CFD simulation, air conditioning system with layered air conditioner plus floor radiation cooling is adopted to improve the indoor environment in large space. The design method of constant temperature, humidity and air-conditioning system in Chinese museum and exhibition hall is discussed.
